US 160NW resists ultraviolet and biological deterioration, rotting, naturally encountered basics and acids. <> Slope protection structures are to be used where concentrated water will cause excessive erosion on existing and/or recent cut and fill slopes. Values shown are based on Table 873.3A dimensions and an assumed specific gravity of 2.65. Place a layer (six inch minimum) of Weight will vary based on density of rock available for the project. Chapter 4: Construction Details, Section 72: Slope Protection, Direction of flow and angle of impingement at various water stages, Capability of adjacent soil types to resist erosion from wash and eddy currents. /Type/ExtGState IMPLEMENTATION OF ROCK SLOPE PROTECTION (RSP) DESIGN Also, ensure the contractor does not drop rock into place; otherwise, cracking or breaking may occur. The finish surface must be roughened by brushing to expose rocks. Slope protection is usually needed to protect the upstream slope against erosion due to wave action.
